HENRY D. OUSHMAN, OF THREE RIVERS, MICHIGAN.

INHALER.

SPECIFICATION forming part of Letters Patent No. 351,744, dated November 2, 1886. 4

' Application filed June lf), [886. Serial No. 205,636. (No model.)

.To all whom it may concern:

. Be it known that I, HENRY D. OUsHM'AN, of Three Rivers, in the county of St. J oseph' and State of Michigan, have invented an Improved Open Stopper for Inhalers, 850., of whichthe following is a full description, reference being bad totlie accompanying drawings.

' The object of my invention is to provide an open or perforated stopper for inhalers, smelling-bottles, and other uses, which is adapted to be self-supporting-that is, to hold itself in posit-ion within a hollow tube, vessel, or cylindrical body, and that can also, if desired, be used in connection with any ordinary stopperof cork, for eXample-as Well as alone.

In the drawings, Figure 1 is a longitudinal sectional view of an inhaler with my stopper applied. Fig. 21s a view of a perforated blank for forming such a stopper as shown in Fig. 1. Fig. 3 is a perforated scalloped blank for forming such a stopper as shown in Fig. 4. Fig. 51s a perforated stopper with a cork in it.

A indicates a perforated blank of metal; or it might be of some peculiar paper, vulcanized fiber, or other substance'having the pro per quality for the use contemplated. This blank can be stamped or punched out of a thin plate of metal, for example-either slitted or scalloped around its margin, as illustrated in Figs. 2 and 3. Then the blank can be formed in suitable dies into cup shape, as is well understood by metal-workers, as shown in Figs. 1 and 4. It will be better to bend the sealloped radial projections of the blank a little, as illustrated.

When the cup-shaped perforated stopper is formed, its margin is notched or slitted, and is be used alone, or an open or closed stopper can be used with it to extend within it, as illustrated, B in Fig. 5 being such a stopper.

I am aware that an open or perforated cupshapeil metal-plate stopper is not broadly new, and I do not claim it; butmy improved open stopper, made from a single piece of thin metal in cup shape, with its rim notched or slotted,

is new, and has marked practical advantages, in that it can be easily, inserted in varyingsized tubes, when it will hold itself in place, and may be adjusted or removed conveniently at will.

Having described my invention, What I claim, and desire to secure by Letters Patent of the United States, is-

As a new article of manufacture. an open or perforated cup-shaped stopper, 'slitted, scalloped, or-notched aroundits margin, so as to be capable of pressing outward within a tube to hold it in place, substantially as set forth.

In testimony whereof I have hereunto subscribed my name.

HENRY D. cUsHMAN."
